l, E. BIRDSALL CORRESPONDENCE PUZZLE May 2, 1933.

Filed Feb, 25, 193s Patented May 2, 1933 UNITED STATES PATENT OFFICE IDA E. BIRDSALL, F BLOOMFIELD., NEW JERSEY CORRESPONDENCE PUZZLE My invention relates to a correspondence puzzle and it is an object of the same to provide a medium for correspondence which medium shall also embody attractive and `advantageous features of a puzzle.

Referring to the drawing which is made a part of this application and in which similar reference characters indicate similar parts:

Fig. 1 illustrates one side face of the device of my invention,

Fig. 2 illustrates the other side face, and Fig. 3 is a section on line 3-3 of Fig. 1. In the drawing reference character 10 indicates a sheet of correspondence paper on which may be Written a letter in ordinary manner. The sheet of correspondence paper has jig saw puzzle elements 11 alxed to what may be called the rear face of the sheet, i. e., the one that is not written on. These jig saw puzzle elements Preferably bearv a design in accordance with the well known practice and are afiiXed in their normal relation to the sheet of correspondence paper by some such means as paste or glue. One suitable design is illustrated in Fig. 1 but any desirable design'may be employed. f

' Thefa'ce of the correspondence paper upon which the letter Vis to be written is illustrated Vin Fig; 2 and preferably indications are provided on this face correspondingto the shape of the jig saw puzzle elements on the rear face. In this instance I have illustrated such indications as consisting of dotted lines 12, as a matter 'of convenienceybut preferably they will consist of faint colored lines so as to contrast slightly with the paper and so as not to mar the appearance of the correspondence sheet unduly, but any suitable device for indieating on the front face of the paper the shape 4o of the elements aixed to vthe rear face may be used according to convenienceor desire. A

In the use of my device a"le'tter will be written on the exposed face of thecorrespondence sheet and then this sheet will be severed along the lines 12 so that the entire device now consists of jig saw puzzle elements bearing parts of the design of Fig. 1 on one face and having on the other face parts of the letter written on the correspondence sheet.

This mass of elements may then be enclosed -it will be possible to read the letter.

in any convenient container and mailed in ordinary manner. The recipient now upon receiving the missive must first assemble the parts in the manner of a jig saw puzzle before It will be understood, that, while the elements 11 are'preferably completely severed andl thus independently aiXed to the correspondence sheet they may be only partially severed or a plate or sheet of suitable material for a jig saw puzzle may merely have the design imprinted or otherwise located upon one face thereof and then have the correspondence sheet aixed by glue or otherwise to the plain faceof such a sheet of jig saw material, after which the letter may be written and the elements severedin any conventional or desirable manner.

Having thus fully described my said i11- vention, what I claim as new and desire to secure by Letters Patent is:

A correspondence puzzle comprising a laminated structure including as one layer a sheet of writing paper and as another layer take-apart and put-together elements of substantial thickness, substantially severed from each other` and secured in face-to-face contact with the sheet of writing paper, said sheet having' on its exposed face lines following the lines of division between said take-apartl and put-together elements, substantially as set forth.

In testimony whereof I ailiX my signature.
